Subject: [PATCH tip/core/rcu 3/3] srcu: Remove KCSAN stubs
Date: Mon, 22 Jun 2020 17:33:33 -0700	[thread overview]
Message-ID: <20200623003333.26611-3-paulmck@kernel.org> (raw)
In-Reply-To: <20200623003310.GA26539@paulmck-ThinkPad-P72>

From: "Paul E. McKenney" <paulmck@kernel.org>

KCSAN is now in mainline, so this commit removes the stubs for the
data_race(), ASSERT_EXCLUSIVE_WRITER(), and ASSERT_EXCLUSIVE_ACCESS()
macros.
